Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Forms the body of the hash and is warmed through in the gravy.
- Flour
- Thickens the dripping and water into a smooth gravy.
- Onions
- Soften and brown in the fat, adding sweetness and savory flavor.
- Dripping
- Carries the flavor and browns the onions in the saucepan.
The step that matters
Stirring in the flour before the water. Cooking the flour in hot fat for a moment removes its raw taste. Adding the water gradually while stirring prevents lumps and gives a smooth gravy.
Swap the onion
How well each one fits the dish's main ingredients (meat, flour, pepper):
- Shallotfits better
- Capsicumfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against meat, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
